FILLING-'REPLENISHING LO'OM.

SPECIFICATION forming part of Letters Patent No. 763,441, dated June 28,1904. Application filed January 8, 1904. Serial No. 188,176- (No model.)

Ton, whom it may concern.-

Be it known that I, WALLAoE I. STIMPsoN, a citizen of the United States,residing at Milford, county of WVorcester, and State of Massachusetts,have invented an Improvement in Automatic Filling-Replenishing Looms. ofwhich the following description, in connection with the accompanyingdrawings, is a specification, like characters on the drawingsrepresenting like parts.

This invention relates to looms provided with means for automaticallyreplenishing the running filling, and particularly to looms of suchclass known technically as feelerlooms,'wherein the fillingreplenishment is effected prior to complete exhaustion of the supply offilling in the active shuttle.- This changing or replenishment of thefilling prior to complete exhaustion of the supply contained in therunning shuttle is designed to prevent the possibility of thin placesbeing made in the cloth, because the change is made before the fillingcompletely runs out, and hence there should be no pick occurring inwhich filling is either wholly absent or extending only part way acrossthe cloth. The filling-replenishing mechanism is controlled as to thetime of its operation by the feeler, which intermittingly engages andfeels the filling in the running shuttle, and a filling fork or detectoris used to detect failurez'. 0. breakage of filling-and when detected toeffect stoppage of the loom. Such filling-detector is located at theside of the loom opposite that at which the replenishing mechanism isplaced, and in actual practice if the filling breaks so as to leave along end dragging from the shuttle it frequently will tilt thefilling-fork just as if the filling were intact and a mispick is made.Manifestly this might continue for a number of picks and no fillingwould be laid, producing a thin place in the cloth of greater or lesswidth. In my present invention I'have overcome this objection byproviding a second filling-detector, located at the opposite side of theloom and arranged also to effect stoppage of the loom upon detection offilling failure. With the second detector if a dragging or trailing endis present it will be carried so far into the shuttleboX at thereplenishing side of the loom that such second detector will detect thefilling failure and operate to stop the loom, so that when necessary theweaver can readily match the pick byvhand. I have also provided meanswhereby detecting actionof either filling-detector is adapted to arrestthe operation of a take-up instrumentality, so that no thin place can bemade. I

My present invention therefore comprehends, in a-loom provided withmechanism to furnish fresh filling prior to complete exhaustion of. thesupply of filling in the running shuttle, two filling-detectors todetect filling failure on alternate picks and adapted to arrest theoperation of a take-up instrumentality when filling failure is detectedby either detector and stopping means for the loom operated by orthrough detecting action of. either detector.

The various novel features of my invention will be fully described inthe subjoined specification and particularly pointed out in thefollowing claims.

Figure 1 is a top or plan view, centrally broken out, of a sufficientportion of a loom to be understood with one embodiment of my presentinvention applied thereto; and Fig. 2 is a front elevation, enlarged andalso contrally broken out, of a portion of the apparatus shown in Fig.1.

The lay A having shuttle 'boXes B B thereon, the breast-beam A, havingat one end the notched holding-plate N for the shipper S, forming a partof the loom-stopping means, and thefilling-feeder F, mounted on theother end of the breast-beam, the transferrer f to remove thefilling-carriers o one by one from the feeder and insert them in theautomatically-self-threading shuttle S having a thread-delivery eye atits right-hand end viewing Fig. 1, may be and are all of usualconstruction and operate in well-known manner. A knock-off lever n,fulcrumed at a on the breast-beam and adapted to release the shipperfrom its holding-notclnhas its inthe arm 14 enters the slot 91 of theknock-off lever, so that the member 13 will be rocked when the slide fis moved forward, and arm 15 extends upward in front of the slide sothat outward movement of the latter will also turn said rocking member13. Consequently whichever detector detects filling failure the shipperwill be released directly by the movement of slide f and through arms 15and 14 and the connecting rocking member 13 by the movement of slide 9to stop the loom. A depending arm 16 is secured to the member 13, whicharm in practice is arranged to arrest the operation of a take-upinstrumentality whenever the member 13 is turned. Such take-upinstrumentality is included as a part of an organized loom and may be ofany suitable construetion-sueh, for instanee,as shown in United StatesPatent No. 643,284c-and' in that case the arm 16 would when rockedcooperate with the take-up pawl-carrier to arrest its operation. Thedetecting action of either detector is thereby arranged to arrest theoperation of the take-up instrumcntality on the detected pick, and itwill be manifest from Fig. 1 that the detectors act on alternate picksto detect presence or absence of the filling. Should a trailing end offilling prevent the detector from detecting the failure of the filling,it will not interfere with the detecting action of the other detector,g, because when the shuttle is in the box B the thread-eye is nearestthe outer end of the box and the trailing filling is drawn out of thepath of the detector g and its slide will be moved outward, releasingthe shipper by or through the operation of the rocking member 13, as hasbeen described. A single spring 17, secured to a fixed part of theloom-frame and bearing upon the arm 1 1, suffices to return both slidesf to their normal position after they have been moved outward.

I have shown and described one practical embodiment of my inventionwithout attempting to illustrate or explain various modificaetions,changes, or rearrangements which would occur to those skilled inthe art, as the same may be made without departing from the spirit andscope of my invention and are not necessary to the proper understandingthereof.

Having fully described my invention, what I claim as new, and desire tosecure by Letters the filling in the running shuttle, twofillingdetectors, located at opposite sides of the loom and adapted toarrest the operation of a takeup instrumentality when filling failure isdetected by either detector, and stopping means for the loom operated byor through detecting action of either detector.

3. In a loom, mechanism to provide the running shuttle with freshfilling prior to complete exhaustion of the filling therein, twofilling-detectors to detect filling failure on alternate picks andadapted to arrest the operation of a take-up instrumentality whenfilling failure is detected, a shipper, and means to effect release ofthe same when either detector detects filling failure.

4. In a loom, filling-replenishing mechanism, means to control the timeof its operation, including a feeler to intermittingly engage thefilling in the running shuttle, two filling-detectors located atopposite sides of the loom and adapted to govern the operation of atake-up instrumentality, a shipper, and releasing means thereforoperated by or through either detector upon detection of filling failurethereby.

5. In a loom, filling-replenishing mechanism, means to cause theoperation thereof prior to exhaustion of the filling in the runningshuttle, filling-detectors at opposite sides of the loom, a shipper,releasing means therefor, including a rocking member extending acrossthe loom, and operating connections between said rocking member and bothof said fillingdeteetors whereby said rocking member is operated wheneither detector detects failure of filling.

6. In a loom, filling-replenishing mechanism, means to cause theoperation thereof prior to exhaustion of the filling in the runningshuttle, filling-detectors at opposite sides of the loom, a shipper,releasing means therefor, including a rocking member extending acrossthe loom, a device connected therewith adapted to arrest the operationof a take-up instrumentality when said member is rocked, and operatingconnections between both detectors and the rocking member whereby thelatter is operated when either detector detects failure of filling.
